Visits to London of this kind were kept up for some years at the cost of much exertion on his part. I have often heard him speak of the wearisome drives of ten miles to or from Croydon or Sydenham--the nearest stations--with an old gardener acting as coachman, who drove with great caution and slowness up and down the many hills. In later years, all regular scientific intercourse with London became, as before mentioned, an impossibility.
The choice of Down was rather the result of despair than of actual preference; my father and mother were weary of house-hunting, and the attractive points about the place thus seemed to them to counterbalance its somewhat more obvious faults. It had at least one desideratum, namely quietness. Indeed it would have been difficult to find a more retired place so near to London. In 1842 a coach drive of some twenty miles was the only means of access to Down; and even now that railways have crept closer to it, it is singularly out of the world, with nothing to suggest the neighbourhood of London, unless it be the dull haze of smoke that sometimes clouds the sky. The village stands in an angle between two of the larger high-roads of the country, one leading to Tunbridge and the other to Westerham and Edenbridge. It is cut off from the Weald by a line of steep chalk hills on the south, and an abrupt hill, now smoothed down by a cutting and embankment, must formerly have been something of a barrier against encroachments from the side of London. In such a situation, a village, communicating with the main lines of traffic, only by stony tortuous lanes, may well have been enabled to preserve its retired character. Nor is it hard to believe in the smugglers and their strings of pack-horses making their way up from the lawless old villages of the Weald, of which the memory still existed when my father settled in Down. The village stands on solitary upland country, 500 to 600 feet above the sea,-- a country with little natural beauty, but possessing a certain charm in the shaws, or straggling strips of wood, capping the chalky banks and looking down upon the quiet ploughed lands of the valleys. The village, of three or four hundred inhabitants, consists of three small streets of cottages meeting in front of the little flint-built church. It is a place where new-comers are seldom seen, and the names occurring far back in the old church registers are still well-known in the village. The smock-frock is not yet quite extinct, though chiefly used as a ceremonial dress by the "bearers" at funerals: but as a boy I remember the purple or green smocks of the men at church.
The house stands a quarter of a mile from the village, and is built, like so many houses of the last century, as near as possible to the road--a narrow lane winding away to the Westerham high-road. In 1842, it was dull and unattractive enough: a square brick building of three storeys, covered with shabby whitewash and hanging tiles. The garden had none of the shrubberies or walls that now give shelter; it was overlooked from the lane, and was open, bleak, and desolate. One of my father"s first undertakings was to lower the lane by about two feet, and to build a flint wall along that part of it which bordered the garden.
The earth thus excavated was used in making banks and mounds round the lawn: these were planted with evergreens, which now give to the garden its retired and sheltered character.
The house was made to look neater by being covered with stucco, but the chief improvement effected was the building of a large bow extending up through three storeys. This bow became covered with a tangle of creepers, and pleasantly varied the south side of the house. The drawing-room, with its verandah opening into the garden, as well as the study in which my father worked during the later years of his life, were added at subsequent dates.
Eighteen acres of land were sold with the house, of which twelve acres on the south side of the house formed a pleasant field, scattered with fair-sized oaks and ashes. From this field a strip was cut off and converted into a kitchen garden, in which the experimental plot of ground was situated, and where the greenhouses were ultimately put up.
The following letter to Mr. Fox (March 28th, 1843) gives among other things my father"s early impressions of Down:--
"I will tell you all the trifling particulars about myself that I can think of. We are now exceedingly busy with the first brick laid down yesterday to an addition to our house; with this, with almost making a new kitchen garden and sundry other projected schemes, my days are very full. I find all this very bad for geology, but I am very slowly progressing with a volume, or rather pamphlet, on the volcanic islands which we visited: I manage only a couple of hours per day and that not very regularly. It is uphill work writing books, which cost money in publishing, and which are not read even by geologists. I forget whether I ever described this place: it is a good, very ugly house with 18 acres, situated on a chalk flat, 560 feet above sea. There are peeps of far distant country and the scenery is moderately pretty: its chief merit is its extreme rurality. I think I was never in a more perfectly quiet country. Three miles south of us the great chalk escarpment quite cuts us off from the low country of Kent, and between us and the escarpment there is not a village or gentleman"s house, but only great woods and arable fields (the latter in sadly preponderant numbers) so that we are absolutely at the extreme verge of the world. The whole country is intersected by foot-paths; but the surface over the chalk is clayey and sticky, which is the worst feature in our purchase. The dingles and banks often remind me of Cambridgeshire and walks with you to Cherry Hinton, and other places, though the general aspect of the country is very different. I was looking over my arranged cabinet (the only remnant I have preserved of all my English insects), and was admiring Panagaeus Crux-major: it is curious the vivid manner in which this insect calls up in my mind your appearance, with little Fan trotting after, when I was first introduced to you. Those entomological days were very pleasant ones. I am VERY much stronger corporeally, but am little better in being able to stand mental fatigue, or rather excitement, so that I cannot dine out or receive visitors, except relations with whom I can pa.s.s some time after dinner in silence."
I could have wished to give here some idea of the position which, at this period of his life, my father occupied among scientific men and the reading public generally. But contemporary notices are few and of no particular value for my purpose,--which therefore must, in spite of a good deal of pains, remain unfulfilled.
His "Journal of Researches" was then the only one of his books which had any chance of being commonly known. But the fact that it was published with the "Voyages" of Captains King and Fitz-Roy probably interfered with its general popularity. Thus Lyell wrote to him in 1838 ("Lyell"s Life," ii. page 43), "I a.s.sure you my father is quite enthusiastic about your journal...and he agrees with me that it would have a large sale if published separately. He was disappointed at hearing that it was to be fettered by the other volumes, for, although he should equally buy it, he feared so many of the public would be checked from doing so." In a notice of the three voyages in the "Edinburgh Review" (July, 1839), there is nothing leading a reader to believe that he would find it more attractive than its fellow-volumes. And, as a fact, it did not become widely known until it was separately published in 1845. It may be noted, however, that the "Quarterly Review" (December, 1839) called the attention of its readers to the merits of the "Journal" as a book of travels. The reviewer speaks of the "charm arising from the freshness of heart which is thrown over these virgin pages of a strong intellectual man and an acute and deep observer."
The German translation (1844) of the "Journal" received a favourable notice in No. 12 of the "Heidelberger Jahrbucher der Literatur,"
1847--where the Reviewer speaks of the author"s "varied canvas, on which he sketches in lively colours the strange customs of those distant regions with their remarkable fauna, flora and geological peculiarities." Alluding to the translation, my father writes--"Dr.
Dieffenbach...has translated my "Journal" into German, and I must, with unpardonable vanity, boast that it was at the instigation of Liebig and Humboldt."
The geological work of which he speaks in the above letter to Mr. Fox occupied him for the whole of 1843, and was published in the spring of the following year. It was ent.i.tled "Geological Observations on the Volcanic Islands, visited during the voyage of H.M.S. "Beagle", together with some brief notices on the geology of Australia and the Cape of Good Hope": it formed the second part of the "Geology of the Voyage of the "Beagle"," published "with the Approval of the Lords Commissioners of Her Majesty"s Treasury." The volume on "Coral Reefs" forms Part I. of the series, and was published, as we have seen, in 1842. For the sake of the non-geological reader, I may here quote Professor Geikie"s words (Charles Darwin, "Nature" Series, 1882.) on these two volumes--which were up to this time my father"s chief geological works. Speaking of the "Coral Reefs," he says:--page 17, "This well-known treatise, the most original of all its author"s geological memoirs, has become one of the cla.s.sics of geological literature. The origin of those remarkable rings of coral-rock in mid-ocean has given rise to much speculation, but no satisfactory solution of the problem has been proposed. After visiting many of them, and examining also coral reefs that fringe islands and continents, he offered a theory which for simplicity and grandeur strikes every reader with astonishment. It is pleasant, after the lapse of many years, to recall the delight with which one first read the "Coral Reefs"; how one watched the facts being marshalled into their places, nothing being ignored or pa.s.sed lightly over; and how, step by step, one was led to the grand conclusion of wide oceanic subsidence. No more admirable example of scientific method was ever given to the world, and even if he had written nothing else, the treatise alone would have placed Darwin in the very front of investigators of nature."
It is interesting to see in the following extract from one of Lyell"s letters (To Sir John Herschel, May 24, 1837. "Life of Sir Charles Lyell," vol. ii. page 12.) how warmly and readily he embraced the theory. The extract also gives incidentally some idea of the theory itself.
"I am very full of Darwin"s new theory of Coral Islands, and have urged Whewell to make him read it at our next meeting. I must give up my volcanic crater theory for ever, though it cost me a pang at first, for it accounted for so much, the annular form, the central lagoon, the sudden rising of an isolated mountain in a deep sea; all went so well with the notion of submerged, crateriform, and conical volcanoes,... and then the fact that in the South Pacific we had scarcely any rocks in the regions of coral islands, save two kinds, coral limestone and volcanic!
Yet spite of all this, the whole theory is knocked on the head, and the annular shape and central lagoon have nothing to do with volcanoes, nor even with a crateriform bottom. Perhaps Darwin told you when at the Cape what he considers the true cause? Let any mountain be submerged gradually, and coral grow in the sea in which it is sinking, and there will be a ring of coral, and finally only a lagoon in the centre. Why?
For the same reason that a barrier reef of coral grows along certain coasts: Australia, etc. Coral islands are the last efforts of drowning continents to lift their heads above water. Regions of elevation and subsidence in the ocean may be traced by the state of the coral reefs."
There is little to be said as to published contemporary criticism.
The book was not reviewed in the "Quarterly Review" till 1847, when a favourable notice was given. The reviewer speaks of the "bold and startling" character of the work, but seems to recognize the fact that the views are generally accepted by geologists. By that time the minds of men were becoming more ready to receive geology of this type. Even ten years before, in 1837, Lyell ("Life of Sir Charles Lyell," vol. ii.
page 6.) says, "people are now much better prepared to believe Darwin when he advances proofs of the slow rise of the Andes, than they were in 1830, when I first startled them with that doctrine." This sentence refers to the theory elaborated in my father"s geological observations on South America (1846), but the gradual change in receptivity of the geological mind must have been favourable to all his geological work.
Nevertheless, Lyell seems at first not to have expected any ready acceptance of the Coral theory; thus he wrote to my father in 1837:--"I could think of nothing for days after your lesson on coral reefs, but of the tops of submerged continents. It is all true, but do not flatter yourself that you will be believed till you are growing bald like me, with hard work and vexation at the incredulity of the world."
The second part of the "Geology of the Voyage of the "Beagle"," i.e. the volume on Volcanic Islands, which specially concerns us now, cannot be better described than by again quoting from Professor Geikie (page 18):--
"Full of detailed observations, this work still remains the best authority on the general geological structure of most of the regions it describes. At the time it was written the "crater of elevation theory,"
though opposed by Constant Prevost, Scrope, and Lyell, was generally accepted, at least on the Continent. Darwin, however, could not receive it as a valid explanation of the facts; and though he did not share the view of its chief opponents, but ventured to propose a hypothesis of his own, the observations impartially made and described by him in this volume must be regarded as having contributed towards the final solution of the difficulty." Professor Geikie continues (page 21): "He is one of the earliest writers to recognize the magnitude of the denudation to which even recent geological acc.u.mulations have been subjected. One of the most impressive lessons to be learnt from his account of "Volcanic Islands" is the prodigious extent to which they have been denuded...He was disposed to attribute more of this work to the sea than most geologists would now admit; but he lived himself to modify his original views, and on this subject his latest utterances are quite abreast of the time."
An extract from a letter of my father"s to Lyell shows his estimate of his own work. "You have pleased me much by saying that you intend looking through my "Volcanic Islands": it cost me eighteen months!!! and I have heard of very few who have read it. Now I shall feel, whatever little (and little it is) there is confirmatory of old work, or new, will work its effect and not be lost."
The third of his geological books, "Geological Observations on South America," may be mentioned here, although it was not published until 1846. "In this work the author embodied all the materials collected by him for the ill.u.s.tration of South American Geology, save some which have been published elsewhere. One of the most important features of the book was the evidence which it brought forward to prove the slow interrupted elevation of the South American Continent during a recent geological period." (Geikie, loc. cit.)
Of this book my father wrote to Lyell:--"My volume will be about 240 pages, dreadfully dull, yet much condensed. I think whenever you have time to look through it, you will think the collection of facts on the elevation of the land and on the formation of terraces pretty good."
Of his special geological work as a whole, Professor Geikie, while pointing out that it was not "of the same epoch-making kind as his biological researches," remarks that he "gave a powerful impulse to" the general reception of Lyell"s teaching "by the way in which he gathered from all parts of the world facts in its support."
WORK OF THE PERIOD 1842 TO 1854.
The work of these years may be roughly divided into a period of geology from 1842 to 1846, and one of zoology from 1846 onwards.
I extract from his diary notices of the time spent on his geological books and on his "Journal."
"Volcanic Islands." Summer of 1842 to January, 1844.
"Geology of South America." July, 1844, to April, 1845.
Second Edition of "The Journal," October, 1845, to October, 1846.
The time between October, 1846, and October, 1854, was practically given up to working at the Cirripedia (Barnacles); the results were published in two volumes by the Ray Society in 1851 and 1854. His volumes on the Fossil Cirripedes were published by the Palaeontographical Society in 1851 and 1854.
Some account of these volumes will be given later.
The minor works may be placed together, independently of subject matter.

(An extract from a letter to Lyell, 1847, is of interest in connection with this essay:--"Would you be so good (if you know it) as to put Maclaren"s address on the enclosed letter and post it. It is chiefly to enquire in what paper he has described the Boulders on Arthur"s Seat. Mr. D. Milne in the last Edinburgh "New Phil. Journal"
[1847], has a long paper on it. He says: "Some glacialists have ventured to explain the transportation of boulders even in the situation of those now referred to, by imagining that they were transported on ice floes,"
etc. He treats this view, and the scratching of rocks by icebergs, as almost absurd...he has finally stirred me up so, that (without you would answer him) I think I will send a paper in opposition to the same Journal. I can thus introduce some old remarks of mine, and some new, and will insist on your capital observations in N. America. It is a bore to stop one"s work, but he has made me quite wroth.")

Professor Geikie has been so good as to give me (in a letter dated November 1885) his impressions of my father"s article in the "Admiralty Manual." He mentions the following points as characteristic of the work:--
"1. Great breadth of view. No one who had not practically studied and profoundly reflected on the questions discussed could have written it.
"2. The insight so remarkable in all that Mr. Darwin ever did. The way in which he points out lines of enquiry that would elucidate geological problems is eminently typical of him. Some of these lines have never yet been adequately followed; so with regard to them he was in advance of his time.
"3. Interesting and sympathetic treatment. The author at once puts his readers into harmony with him. He gives them enough of information to show how delightful the field is to which he invites them, and how much they might accomplish in it. There is a broad sketch of the subject which everybody can follow, and there is enough of detail to instruct and guide a beginner and start him on the right track.
"Of course, geology has made great strides since 1849, and the article, if written now, would need to take notice of other branches of inquiry, and to modify statements which are not now quite accurate; but most of the advice Mr. Darwin gives is as needful and valuable now as when it was given. It is curious to see with what unerring instinct he seems to have fastened on the principles that would stand the test of time."
